Effects of active cycle breathing technique on health status, sleep quality, and health-related quality of life of people with chronic obstructive pulmonary

This study is a randomized, single-phase, and unblinded clinical trial.

This study is being conducted at the medical and educational centers of Shahrekord University of Medical Sciences, and due to the nature of the study, blinding was not performed.

Participants completed a written consent form to participate in the study. The age range of patients with chronic obstructive pulmonary disease was 20 to 70 years. The participants' disease was diagnosed by a pulmonologist and confirmed according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria, which are as follows: • Having symptoms of shortness of breath, cough, and increased sputum production or a history of exposure to risk factors • The ratio of forced expiratory volume in 1 second (FEV1) to forced vital capacity (FVC) was less than 0.7 (FEV1/FVC ratio < 70%). (54, 55). The subjects were free of physical and mental problems that would interfere with the learning process. The subjects were free of severe respiratory problems and respiratory failure that would lead to intolerance to the breathing technique.

The control group received only routine care, and the intervention group, in addition to receiving routine care, performed the active cycle breathing technique for 3 months, twice a day, for 15 to 20 minutes each time.

The effect of the active breathing cycle technique on sleep quality is measured using the Pittsburgh Sleep Quality Questionnaire, health-related quality of life with the St. George Questionnaire, and health status with the Chronic Obstructive Pulmonary Assessment Test (CAT) questionnaire.

The method of assigning samples to groups will be in the form of random blocks with different numbers without permutation. For this purpose, first the letter A is considered for the control group and the letter B for the experimental group, and different states of the two groups will be written on the card, and each will be placed in a sealed and opaque envelope. To cover the assignment, blocks with different numbers will be used, that is, blocks of 6 and 2 will be included in the blocks. The block of 6 can be a combination of ABBABA and ... The block of 2 can also include AB, BA. These envelopes are placed in a box and the researcher will not know which group the units under study will be in until the card is selected. Before facing the research units, the ward nurse (unaware of the study and the groups) will determine which group the patients who will enter the study will be in, respectively, by removing one of the envelopes from the box. This process will continue until all the cards are removed from the box, and the cards will be returned to the box again, and this random selection will be repeated until the desired sample size is provided.

Biographical data such as age and gender are essential for better presentation of research results, and since this data is anonymous, there is no reason not to publish it.

Due to the anonymity and coding of the data, they will be available after the study is completed.

This data will be accessible to various health professionals and researchers.

No analysis of this data is permitted and it will only be used for comparison with and citation of results from other studies

The download of the resulting article will be done according to the policy of the journal that publishes it. Therefore, the use of biographical data tables and other sections of the journal is possible after downloading. The email address of the responsible author included in the article will be available for communication with other authors and for guidance.

For this purpose, the applicant can contact the office of the journal that published the article, the corresponding author, and the Vice President for Research of Shahrekord University of Medical Sciences. The duration of access depends on the policy of the journal and the Vice President for Research of the university, but the corresponding author will respond to the request of colleagues within a week.
